Description

Foundry goods plastic cooling device

Technical Field

The utility model relates to a foundry goods plastic cooling device.

Background

The endurance mileage of the pure electric vehicle mainly depends on the battery capacity of the pure electric vehicle, and generally, the more the number of the storage batteries is, the larger the battery capacity is, so that the longer endurance mileage can be obtained. In order to be able to install more batteries on a pure electric vehicle, a battery tray with a sufficiently large size is required. It is known that the battery tray has a cast shape in the production stage, and deformation is inevitable in the casting process and the subsequent cooling process. In addition, the battery tray has thinner wall thickness, and the probability of deformation is several times that of other large castings. If the battery tray after casting is deformed, the dimension and structure obtained by the deformation are wrong, and the structure defects are more obvious after other process steps are operated, for example, the deformed battery tray is out of the punching range or enters the punching range due to the scrap edge part required by normal design in the punching and shearing process, the scrap edge or the part required by actual design is remained on the battery tray after punching and shearing, and the structure defects in the visual range are enough to be judged as scrapped.

Disclosure of Invention

The to-be-solved technical problem of the utility model is how to restrain the deformation of large-scale battery tray in foundry goods drawing of patterns and cooling stage, obtain a foundry goods plastic cooling device from this.

In order to solve the technical problem, the utility model adopts the following technical scheme: the casting shaping and cooling device comprises a punch assembly, an upper shaping and cooling die and a lower shaping and cooling die, wherein an output end for providing power in the vertical direction is arranged on the punch assembly, the upper shaping and cooling die is movably arranged on the punch assembly and is connected with the output end, the upper shaping and cooling die is driven by the output end to move in the vertical direction, the lower shaping and cooling die is fixedly arranged on the punch assembly, the lower shaping and cooling die is positioned in the movement direction of the upper shaping and cooling die, the upper shaping and cooling die comprises an upper die body and a punching and shearing assembly, the punching and shearing assembly comprises a punching knife, a mounting plate, a lifting oil cylinder, a punching and shearing cushion block and a horizontal pushing air cylinder, the cylinder body of the lifting oil cylinder and the cylinder body of the horizontal pushing air cylinder are fixedly connected with the upper die body, the piston rod of the lifting oil cylinder, the mounting panel moves in vertical direction, the piston rod of flat push cylinder with dash and cut cushion fixed connection, it moves in the horizontal direction to dash to cut the cushion, the motion range that dashes and cut the cushion intersects with the motion range of mounting panel and the motion range that dashes and cuts the cushion lies in between mould body and the mounting panel, it is protruding to go up the last plastic that the edge of mould body was equipped with orientation plastic cooling lower mould, the edge of the body of plastic cooling lower mould is equipped with the lower plastic arch of mould on the orientation plastic cooling.

In the technical scheme, the punching and shearing assembly intervenes in time according to the process steps. The position of the punching shear cushion block in the initial state can ensure that the punching cutter is closer to the upper die body and is in a waiting state, so that the upper shaping bulge can clamp the casting together with the lower shaping bulge after the upper die body descends, and the casting can be shaped in the cooling process. After shaping, the upper die body firstly rises, the punching and shearing cushion blocks are convenient to change positions, then the punching and shearing cushion blocks establish a connection relation between the upper die body and the mounting plate for limiting the position of the mounting plate relative to the upper die body, so that the punching knife protrudes towards the casting, the punching knife enters a punching and shearing state, and when the upper die plate descends again, the punching knife contacts with the casting before the casting and punches the waste edge part of the casting. The position change of the punching shear cushion block is based on the telescopic function of the horizontal pushing cylinder, and the position change of the mounting plate relative to the upper die body is based on the telescopic function of the lifting oil cylinder.

In the technical scheme, the specific distribution of the punching cutter, the upper shaping bulges on the upper die body and the specific distribution of the lower shaping bulges on the body of the shaping cooling lower die are adaptively arranged according to the external contour of the casting, and the arrangement is a conventional selective technical means.

The shaping purpose of the large-scale battery tray in the cooling stage is realized through the clamping operation of the casting shaping and cooling device. The cooling process of the large casting generally needs a longer time, and the time is far longer than the fastest punching and shearing time of the punch assembly in the prior art, so the punch assembly works in a state of being lower than the rated power of the punch assembly in the technical scheme, and the clamping elasticity of the punch assembly can be exerted to the maximum extent.

The purpose of changing the position of the punching and shearing cushion block is convenient for adjusting the position relation between the mounting plate and the upper die body, and the punching and shearing cushion block can play a technical contribution of limiting the maximum distance between the mounting plate and the upper die body, namely serving a punching knife to maintain a punching and shearing state. The change in position of the punch shear pad should meet the requirements that it serves the die cutter to maintain the punch shear state and meet the requirements that it does not restrict the die cutter from entering the wait state. The punching shear cushion block is used for maintaining the punching shear state of the punching knife and is necessarily positioned between the upper die body and the mounting plate; the punching shear cushion block can be completely separated from the area between the upper die body and the mounting plate or obtain a movement space which is convenient for the punching knife to be close to the upper die body through a concave-convex staggered structure. Although the space required for the punching knife to enter the waiting state can be obtained in both modes, when the movement space for the punching knife to approach the upper die body is obtained through the concave-convex staggered structure, the time required for changing the position of the punching shear cushion block is shorter than that required for changing the position in other modes. Therefore, the technical scheme is preferred, the punching shear cushion block is provided with a concave-convex surface I, the mounting plate is provided with a concave-convex surface II corresponding to the concave-convex surface I, and the orientation of the concave-convex surface I is opposite to that of the concave-convex surface II. As long as the convex part of the punching shear cushion block at the concave-convex surface I is aligned with the concave part of the mounting plate at the concave-convex surface II, the required movement space for the punching cutter to move towards the upper die body and enter a waiting state is obtained. Therefore, the response speed of the punching and shearing assembly is high, the action is sensitive, and the power consumption is low.

In order to further shorten the time required by changing the positions of the punching and shearing cushion blocks, in the technical scheme, the punching and shearing cushion blocks are distributed between the upper die body and the mounting plate in a symmetrical arrangement mode, and the punching and shearing cushion blocks move synchronously. Compared with the time for changing the position of the punching and shearing cushion block when a single punching and shearing cushion block is used, the time is shortened by half, and the working efficiency is doubled.

The utility model adopts the above technical scheme: the casting shaping and cooling device inhibits the casting deformation in the cooling stage and drives the casting to recover the ideal form in a clamping mode, and based on the original positioning foundation, the waste edge is punched at the same station immediately, so that the shaping and cooling stage and the waste edge punching stage are both based on the same positioning foundation, the repeated positioning operation is avoided, the product quality is improved, the production efficiency is improved, and the labor intensity is reduced.
